I have not been able to find any threads with a write up on how to do this. I have a 0 degree bag with a storage pocket and zipper on the foot. It's a perfect set up to zip it open and have a hole on the inside so I could slide the sleeping bag over the hammock. The current configuration has a double zipper, but It starts about 2 foot from the foot of the bag and I loose all the room by simply zipping it over the hammock.
Anybody have any experience with this, or know of anyone with a write up on how to do it?
